Is Your Banking App Selling Your Data? What to Know
What You Need to Know
— Traditional FDIC-insured banks are subject to strict financial privacy laws under GLBA — your transaction data cannot be sold to unaffiliated third parties without your consent
— FinTech apps that are not banks operate under different rules — some can and do use your financial data for advertising targeting and product matching
— “Sharing” your data is legally different from “selling” it — many privacy policies allow data to be shared with partners without technically selling it
— The specific language to look for in any financial app privacy policy: whether data is used for “marketing,” “advertising,” or “third-party partners”
— You have specific opt-out rights under GLBA and CCPA (in California) — using them limits how your data can be used without closing your account
The Honest Answer: It Depends on What Kind of App It Is
Questions about your banking app selling your data have become increasingly common as more financial activity moves through FinTech platforms. Whether a specific app is selling, sharing, or simply using your financial data depends primarily on what type of company built it. Traditional banks — FDIC-insured institutions subject to the Gramm-Leach-Bliley Act (GLBA) — face strict legal limits on sharing your nonpublic personal financial information with unaffiliated third parties. FinTech apps that are not banks, and that are primarily technology companies rather than financial institutions, may operate under different rules with more latitude to use financial data for advertising, product matching, and affiliate revenue. Understanding which category your app falls into is the first step in understanding how open banking and AI are changing FinTech data practices. The full picture is in the Open Banking & AI FinTech guide.
Credit Karma is a prominent example of the FinTech data model: it provides free financial services funded by using your financial data to target you with relevant product recommendations that pay referral fees when you apply and are approved. This is disclosed in their privacy policy and terms of service. It is not a secret or a violation — it is the explicit business model. The question is whether you understand and accept it before connecting your accounts. The broader context for evaluating financial app data practices is in the FinTech & Modern Money Tools guide.
The Legal Framework: GLBA and What It Covers
The Gramm-Leach-Bliley Act requires financial institutions — banks, credit unions, insurance companies, securities firms — to provide privacy notices explaining their data sharing practices and to give consumers the right to opt out of sharing with unaffiliated third parties for marketing purposes. GLBA does not prohibit all data sharing; it requires disclosure and opt-out rights for specific types of sharing.
What GLBA permits: sharing with affiliated companies, sharing necessary to process transactions, sharing with companies performing services on behalf of the financial institution, sharing as required by law. What GLBA restricts without opt-out: sharing nonpublic personal information with unaffiliated third parties for marketing purposes. Your bank’s annual privacy notice — which most people delete without reading — is the required GLBA disclosure explaining exactly what your bank does with your data.
Non-bank FinTech apps are not always subject to GLBA with the same force as regulated financial institutions. A budgeting app, personal finance platform, or financial data aggregator may be subject to state privacy laws (California’s CCPA most prominently), FTC oversight under general consumer protection authority, and their own stated privacy policies — but not necessarily the same federal financial privacy framework that applies to your bank.
How to Read a Financial App Privacy Policy
Most people skip privacy policies entirely. For financial apps that access your transaction data, the five-minute review described here is worth doing. You are not reading the whole document — you are using Ctrl+F to search for specific terms that reveal the data sharing model.
Search for: “sell” or “selling.” Does the policy explicitly state they do not sell your personal financial information? Reputable financial apps include this language. Absence of this language is a yellow flag.
Search for: “share” or “sharing.” What does the policy say about sharing with third parties, partners, or affiliated companies? Sharing for advertising or marketing purposes is functionally similar to selling in terms of data exposure, even if it is not described that way.
Search for: “marketing” or “advertising.” Is your data used to serve you targeted ads? Is it used to generate product recommendations that pay the company referral fees? Both are legitimate business models when disclosed — but understanding them is part of evaluating the trade-off you are making by using the app.
Search for: “opt out” or “opt-out.” Does the app offer opt-out rights for specific data uses? Using available opt-outs limits how your data can be used for marketing purposes without requiring you to close the account.
You are already sharing your financial data. Understanding how is the starting point.

Frequently Asked Questions
Can my bank sell my transaction data?
Your FDIC-insured bank is subject to GLBA restrictions. It cannot share your nonpublic personal information with unaffiliated third parties for marketing purposes without giving you the right to opt out. It can share data with affiliated companies and service providers. Your bank’s annual privacy notice describes exactly what it shares and with whom — reading it takes five minutes and tells you specifically what your bank does with your data.
Is Credit Karma selling my data?
Credit Karma uses your financial data to target you with product recommendations — credit cards, loans, insurance products — for which it earns referral commissions when you apply and are approved. This is their stated business model, disclosed in their privacy policy and terms of service. They describe this as using data for “personalizing offers” rather than “selling data,” which is technically accurate but functionally similar. Credit Karma states it does not sell your personal information to third parties in the conventional sense of the word.
How do I opt out of financial data sharing?
For your bank: look for your annual GLBA privacy notice, which includes opt-out instructions. You can also call your bank directly and request to opt out of data sharing for marketing purposes. For FinTech apps: check the privacy settings within the app for marketing and data sharing opt-outs. California residents have additional rights under CCPA, including the right to request disclosure of what data is collected and to opt out of certain data sharing practices.
